Y M/EA/roff wf w ing 14 having therein a disk conveyor consisting of a plurality of horizontal carrier disks 1 rotatable about vertical axes and a Series of substantially rectilineal canguides 6 disposed above the disks 1 and Iextending transversely of the casing V151. Each Vof the carrier disks 1 has relatively large periph-` eral teeth 7 and a central vertical bored bulb rotatably cooperable n with a stationary verical journal column 8, YThe journal columns 8 are detachably secured to channel bars 18 by means of clamping nuts 24, the channel bars 18 extending transversely across the cas ing 14 and being att-ached to the casing side walls in any suitable manner. The central hubs of the disks l rest upon thrust collars 1 7 embracing the columns 8 and coacting with l the u per surfaces rof the channel bars A18.

The power shaft 11 is capable of being rotated by vlucana of a pulley which is drivingly connectible Iwith the shaft by means of aclutch 21 l'coutrollable by meansof a lever 12.

vertical axes and a series ofhsubstau'tially `l'ootilineal can (gluides 6 disposed above the and exten ing transversely of the casing 14. The disks 1 of this conveyor are the l same as those of the conveyor of Figs. 1 and e, and the supporting structure for the guides 6 and disks 1 is also similar. Due to the relatively small'size of the exhaust box of Figs. 3 and' 45, all of the disks 1 may, however, be driven by means of a single set of worm gearing comprising a worni 10 and worm wheel 9 applied to a selected disk 1 in a an obvious manner. Thesuccessive cans 13 are delivered to the casing 14`by means of a liable' te any vide su ports for/,the can guides 6, .the guides f disks a rotary supply disk 15 and are discharged from the exhaust box b means of a delivery disk 16 which is rotatable at a higher speed than the supply disk 15 by means of caring 25, 26 The modified exhaust box is n. S0 Pr0- vided with a cover lfcoacting with a liquid seal associated with the wall of the casin 14.

i ith reference to the direction of travel of .the successive cans .over the carrier disks, the disks 1k oaf the improved conveyor are arranged in rows 3, 4, 5 extendin longitudinally of the guides 6 and cooperale to transport the kcans in substantially rectilineal opposite directions. For convenience of descripti `y,' reference will be made to the three rows o disks 1 nearestto the inlet of the .exhal be alfhu h .the Seme description is ihrae, ad'pining 'rows pf Tlwdlsk .of thesis rows 3, here all Fogfllle in the same direction and .have rPerl valise wipourV een 7 o: me disks of t e intermediaterow 4 the latter boing oaun inthe Qpppsie dimm.

`The device is obviously capable offtrans'portingfcans 13 of various diameters, vbut the smaller the cans, thegreater the waste yof transferring surface becomes. The 4improvement however `permitsutilization of both sides of the transporting surfacesA of all of the inner disksv 1,"by virtue of the rectilineal travel of the cans 13 thereover.

By providing peripheral teeth 7 of relatively large size, the transfer of cans 13 from one disk 1 to an adjoining disk is effected more gently than if smaller teeth are used, and the cans are not so apt to be damaged by unevenness due to non-alinement of the transporting surfaces of the adjoining disks. The larger teeth also facilitate accurate construction of the disks 1 and are more readily cleaned. If a large number ofA disks 1 are utilized, it is preferable to provide a. plurality of independent drives for selective groups of the disks as shown in Fig. 1, in order to Vinsure uniform rotation of all of the disks and prevent the cans13 from jamming due to lost motion between the cooperating disk teeth 7 Jamming of the cans 13 is also prevented by causing the discharge vdisk 16 to rotate at a higher rate of speed than the disks 1, so that free delivery of the treated cans is insured. With the provision of a common control lever 12 for simultaneously controlling the supply of cans 13 and the H operation of the transporting mechanism, the

supply of cans is automatically stopped in case it becomes necessary to stop the conveyor. It will thus be notedthat the present improvement provides various precautions for preventing injury of the objectsl being transported and for insuring gentle and uniform transportation of the successive cans through the treating zone.

The entire mechanism is moreover readily f accessible for inspection and cleaning. By

removing the cover 19the operation is observable without obstruction. The guides 6 which are supported solely by the columns 8, are freely vertically removable from their supports. After the guides 6 have been removed, the disks 1 are likewise freely vertically removable independently of each other. The columns 8 may be removed fromthe channels 18 upon release ofthe nuts24 and' the channels may be detachably associated with the walls of the casing 14, thus permitting convenient removal of all elements `of the structure.

It should be understood that it is not desired to limit the inventionto ,the exact details of construction and operationhereinl r cur to persons skilled in the art.
